| implications of cysteine metabolism in the heavy metal response in trichoderma harzianum and in three fusarium species. | we studied the ability of four different fungal species, trichoderma harzianum, fusarium antophyllum, fusarium compactum and fusarium phyllophilum, to grow in the presence of heavy metals, and monitored their cysteine and glutathione content and the activity of o-acetylserine(thiol)lyase (oastl), which is involved in cysteine biosynthesis. zn and pb did not affect fungal growth or sporulation at the concentrations used, whereas cd and hg did. in most cases, cysteine and glutathione content was h ... | 2009 | 19298998 |
| metabolites inhibiting germination of orobanche ramosa seeds produced by myrothecium verrucaria and fusarium compactum. | myrothecium verrucaria and fusarium compactum were isolated from diseased orobanche ramosa plants collected in southern italy to find potential biocontrol agents of this parasitic weed. both fungi grown in liquid culture produced metabolites that inhibited the germination of o. ramosa seeds at 1-10 mum. eight metabolites were isolated from m. verrucaria culture extracts. the main metabolite was identified as verrucarin e, a disubstituted pyrrole not belonging to the trichothecene group. seven co ... | 2005 | 15740046 |
| novel triterpene sulfates from fusarium compactum using a rhinovirus 3c protease inhibitor screen. | two novel triterpene sulfates have been isolated from fusarium compactum by bioactivity-directed fractionation using an assay which measures the inhibition of proteolytic activity of rhinovirus 3c protease on a fluorogenic peptide substrate. the compounds were purified by countercurrent and reverse phase chromatographies. nmr, ms, uv and ir studies revealed two triterpene sulfates, uncommon metabolites of terrestrial fungi. | 1996 | 8698636 |
| the influence of genotype and environment on the physiological and metabolic diversity of fusarium compactum. | fungal species produce a large variety of secondary metabolites which are of considerable interest to the pharmaceutical industry. it is clear that the secondary metabolite production of a species varies significantly in strains from different geographic locations and from different habitats. the influence of genotype and environment on metabolite production is, however, poorly understood. in this study we examined the influence of genotypic variability, physiological variability, environmental ... | 1996 | 9045756 |
| pectinolytic and cellulolytic enzymes enhance fusarium compactum virulence on tubercles infection of egyptian broomrape. | the use of enzyme could facilitate pathogen penetration into plant host. here the combination of cellulase and pectinase was ascertained on the pathogenicity of f. compactum (1.4 × 10(6) propagules ml(-1)) on broomrape tubercles. f. compactum alone infected all the inoculated tubercles but did not kill any significant number. infested tomato roots that were inoculated with mycelia plus pectinase (20 u ml(-1)) had over 50% tubercles dead one week after treatment. those inoculated with mycelia pl ... | 2010 | 21318162 |
